Conference Cancer · January 1, 2025 BACKGROUND: Dermatofibrosarcoma protuberans (DFSP) is a cutaneous sarcoma with an infiltrative growth pattern that makes it challenging to clear margins. High quality data regarding DFSP natural history, management, and outcomes are limited. METHODS: Data ... Full text Link to item Cite

Abstract B052: Single-cell and spatial analysis of the immune landscape unveils a subset of potentially tumor-reactive T cells in patients with localized PDAC

Conference Cancer Research · September 15, 2024 AbstractEven in its localized stages, pancreatic ductal adenocarcinoma (PDAC) is virtually incurable, characterized by early dissemination and disease recurrence. The liver is the most common site of metasta ... Full text Cite

Phase I trial of talimogene laherparepvec for the treatment of peritoneal surface malignancies (TEMPO).

Conference Journal of Clinical Oncology · June 1, 2024 2668Background: Peritoneal surface malignancies (PSM) constitute a group of difficult-to-treat metastatic diseases that respond poorly to standard chemotherapy.

Is There a Role for Surgery in Patients with Neuroendocrine Tumors of the Esophagus? A Contemporary View from the NCDB.

Conference Ann Surg Oncol · March 2020 BACKGROUND: Esophageal neuroendocrine tumors (eNETs) are exceedingly rare, aggressive and have a poor prognosis. Treatment guidelines are ill-defined and mainly based on evidence from case reports and analogous experiences drawn from similar disease sites. ... Full text Link to item Cite

Nationwide trends and outcomes associated with neoadjuvant therapy in pancreatic cancer: An analysis of 18 243 patients.

Conference J Surg Oncol · August 2017 BACKGROUND: Neoadjuvant therapy has theoretical benefits for pancreatic cancer; however, its association with perioperative outcomes remains controversial. This study sought to evaluate variation in use of neoadjuvant therapy and outcomes following pancrea ... Full text Link to item Cite

Going the Extra Mile: Improved Survival for Pancreatic Cancer Patients Traveling to High-volume Centers.

Conference Ann Surg · August 2017 OBJECTIVE: This study compares outcomes following pancreaticoduodenectomy (PD) for patients treated at local, low-volume centers and those traveling to high-volume centers. BACKGROUND: Although outcomes for PD are superior at high-volume institutions, not ... Full text Link to item Cite

Minimally Invasive Pancreaticoduodenectomy Does Not Improve Use or Time to Initiation of Adjuvant Chemotherapy for Patients With Pancreatic Adenocarcinoma.

Conference Ann Surg Oncol · March 2016 BACKGROUND: The modifiable variable best proven to improve survival after resection of pancreatic adenocarcinoma is the addition of adjuvant chemotherapy. A theoretical advantage of minimally invasive pancreaticoduodenectomy (MI-PD) is the potential for gr ... Full text Link to item Cite
